摘　　要：国内蓝晶石矿床数量较少,通过对陕西省城固县毕家河-之字坝蓝晶石矿床的矿区地质填图,施工探槽、钻探等工程勘查,基本查明了本地区蓝晶石矿床产出的矿床地质特征,并对矿源的产出进行了探讨,初步认为该矿产的产出受变质热液、构造及高压等综合因素的影响,矿产的形成经历两个阶段,整套小北河片岩可能为矿源层;同时该矿床可为国内同类矿床的勘查借鉴和参考。There are few kyanite deposits in China.Through geological mapping,construction trench and drilling engineering exploration of Bijiahe-Zhiziba kyanite deposit in Chenggu County,Shaanxi Province,the geological characteristics of the kyanite deposit in this area are basically identified,and the occurrence of the ore source is discussed.It is preliminarily considered that the production of the kyanite deposit is synthesized by metamorphic hydrothermal fluid,structure and high pressure.Influenced by these factors,the formation of the mineral resources has gone through two stages,and the whole set of Xiaobeihe schist may be the source bed.At the same time,the deposit can be used as a reference for the exploration of similar deposits in China.
